Hi,
WCT-5WTXAUTO is a 5w 3-coil tx charger. BTW, I want to make a 1-coil tx charger
On the side of HW, some unnecessary blocks would be able to be removed : coil selection-related TR, etc...
Then how about SW-side? I'm using SDK4.0. I found some coil-related variables.
#define NUM_COILS_PER_DEVICE 1u//3u
And then, I modified following ARRAY variables which controlled 3 coils originally.
BYTE byCoilIds[NUM_DEVICES][NUM_COILS_PER_DEVICE] = {{ 0u } }; //{2,1,0}; // set coil combinations by customer
#define PWM_CHANNEL_MAPPING { 3u }//{ 3u, 3u, 3u }
#define COIL_ENABLE_CONTROL_PORTS { (STANDARD_REGISTER_SIZE *) &GPIOC_DR, }
#define COIL_ENABLE_CONTROL_BIT_MASKS { 0x2000u}
#define COIL_DISCHARGE_CONTROL_PORTS { (STANDARD_REGISTER_SIZE *) &GPIOB_DR }
#define COIL_DISCHARGE_CONTROL_BIT_MASKS { 0x80u}
And also EEdata_FlashDefaults.asm was modified to have only 1 coil parameters..
I wonder if it's enough for 1-coil migration. .
Pls help me if you have any experience on it.
Thanks & BR,
Devin
Hi Devin,
For Single Coil design, I rather recommend you to use the WCT-15WTX1COILFF which is a single-coil fixed frequency wireless charging transmitter reference design uses the WCT10xx transmitter controller IC that integrates all required functions for the Wireless Power Consortium (WPC) Qi-compliant wireless power transmitter design.
Currently, the design is under preproduction, but you can access some documentation with a signed NDA with your distributor.
Regards,
Jose
